@Lily1963,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I understand you are getting an error message related to Ink cartridge error on your HP OfficeJet Printer. Don't worry I'll be glad to assist you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Are you using genuine HP Ink cartridges or refilled cartridges?

Have you tried to clean the ink cartridge contacts as well as the electrical contacts?

In the meantime, let's try these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.

Alternatively, I would suggest you try the steps suggested in the support document for - HP Officejet 4500 (G510) Series and 4500 (K710) Series All-in-One Printers - 'Incorrect Print Cartri...
